About this worksheet
Suits Years 3 to 5Angles to sort by size family: acute (sharper than a square corner), right (exactly the corner), obtuse (wider than the corner).
The reference is always 90 degrees, and any book corner supplies it. Classification comes BEFORE measurement in angle education: first the families, then the protractor.

Common questions
A memory hook for the names?
Acute means sharp, a cute little angle; obtuse rhymes with the goose that waddles wide. Silly hooks hold: that is their job.
Does the length of the arms matter?
Not a bit, and this is THE misconception: a tiny drawing of a wide angle is still obtuse. The angle is the amount of turn between the arms, not the ink used to draw them.
